Grouped Bar Visuals

While bar charts show comparisons among categories, grouped bar charts show clustered groups of
related measurements as bars.

The following steps demonstrate how to create a new grouped bar visual representation of ethnic
distribution of population in some US Counties. We are using the US
Counties dataset [data source us-counties.csv.zip]. See Importing Data
and Creating Datasets.

Note that the shelves of the visual changed. They are now X Axis,
Y Axis, Colors,
Tooltips, Drill,
Labels, and Filters.

The mandatory shelves are X Axis and Y
Axis. Note also that the fields placed on these two shelves may be easily
swapped by switching X and Y. Doing this
produces a horizontal chart.

Populate the shelves from the available fields (Dimensions,
Measures, and so on) in the Data menu.

Under Dimensions, select Ctyname field and
drag it over X Axis shelf on the main part of the screen. Drop to
add it to the shelf. At this point, we recommend that you alias the field as County; see
Alias.

Select Wa male field and drag it to the Y
Axis shelf. This first measurement provides the axis definition.

Add the other measurements to the Colors shelf. Together with
the measurement on the Y Axis, this creates the 'group' Arcadia Instant uses to draw grouped
bars.

Alias the field on the Y Axis shelf as 'White', and
alias the fields on the Colors shelf as 'Black or African
American', 'American Indian and Alaska Native', 'Asian American',
'Native Hawaiian and Other Pacific Islander', and 'Two or More
Races'.

Add the field Stname to the Filters shelf, and select the value 'Alaska'.

Click Refresh Visual.

The grouped bars visual appears.

Click (pencil icon) next to the title of the
visualization to edit it, and enter the new name.
